A serial builder, looking for a next role — or the backing to launch what I have already built. Ten products and nine published libraries, eight of which you can use or run today. This year alone I have taken them from a problem to something running — and every number on this site is one you could check.
Voice as a vital sign. A patient records five short tasks a day in their own language, and Voxtar measures tremor, breathiness and timing against that person’s own baseline — then flags the drift.
Best oral presentation — West African College of Physicians, July 2026, University of Ibadan, before a panel of consultants. The numbersVoice triage on the queue, with escrowed payment, so an emergency admission is not held up at a cashier’s desk. Designed, not yet built — the page says so.
The numbersThe missing proof layer for YouTube. The best teaching is already free — what is missing is evidence you can do the work at the end of it.
Graded labs, not a quiz: code that passes hidden tests, a model that reconciles, a deck that survives checks. The numbersLearning by domain isomorphism. Bring what you already know, and it maps that structure onto what you want to learn — then teaches you exactly where the mapping breaks.
The numbersA daily drill bot for MB BS Part III. Telegram quiz polls each morning, marked automatically, with a leaderboard at close of play — because solo spaced repetition is a solved problem that almost nobody sustains alone.
155 students · 71,377 limbs marked at 75.47% · ₦47,900 from 25 payers. The numbersDocument retrieval with no chunking, no embeddings and no vector database. A PDF has no headings — only glyphs with a size and a position — so Vectorless rebuilds the structure from the page geometry and navigates to the exact section, tables included.
On FinanceBench: all evidence found, and the section it points at went from 183 pages to 6. The numbersThe parts of NotebookLM I actually use, on my own keys and my own machine. One Hono app serves the web build and the desktop build, so there is a single server to reason about rather than two.
MIT, and the whole of it runs locally — Postgres compiled into the app rather than a database to install. The numbersWebhook observability with nothing to install. A public URL forwards Stripe or GitHub straight to your localhost, because the browser tab itself is the tunnel agent — and every event is captured, replayable and signature-checked.
The stream is held in a Cloudflare Durable Object, which is what makes leaving it open all day cost nothing. The numbersA storefront built so an agent can shop it, not just a person — Java 21 and Spring Boot across four modules, with the catalogue, the cart and the conversation behind one set of contracts.
Hybrid search with no Elasticsearch — full-text and vectors reconciled inside Postgres. The numbersLend a device without losing it. Custody moves between two people by compare-and-swap, so two phones can never both believe they hold the same thing.
The API has zero npm dependencies — Bun’s own runtime is the whole server, and it compiles to one executable. The numbersWe do not guess what matters in a system. We measure it, then publish what the measurement said — including the parts that went against us.
Our headline number today is a benchmark, not an install count.
| Measure | Before | After |
|---|---|---|
| Evidence-page coverage | 0.800 | 1.000 |
| Cost per document | $0.017–0.095 | $0.0003–0.0015 |
| Time per document | 103–840 s | 12–143 s |
| Generative calls per document | 1 | 0 |
| Median span holding a gold page | 183 pages | 36 pages |
When adoption is the number worth showing, it will be the one here.
Healthcare. Voxtar leads, with an IRB application at UCH for a post-thyroidectomy voice cohort as the current priority. Cervical screening, oncology pharmacology and HIV-resistance genomics run behind it. Every clinical product plugs into one shared record core instead of rebuilding it.
Research. Systematic reviews, mechanistic modelling, and checking that a model found real signal rather than a shortcut in the data. Nothing ships from this pillar — it is the standard the other two are held to, applied whether the output is a manuscript or a product.
Education. A cohort of 176 came through three evenings in August. Coursified turns open video into graded courses, Hypatia teaches a new field through one you already know, and MB3 Prepbot drills a medical finals syllabus every morning.
Vectorless — Apache 2.0. Document retrieval with no chunking, no embeddings and no vector database. It rebuilds a document’s structure from the geometry of the page and navigates to the exact section — tables included.
llmgate — Apache 2.0. One Go client over Anthropic, OpenAI and Gemini, with routing, fallback and cost tracking on top. LiteLLM, for Go.
pdfgrab — MIT. A Go port of pdfplumber: positioned words, font sizes, bounding boxes and table detection. It is what lets Vectorless read a page at all.
Every product above runs on these three. Nothing rebuilds them — which is how six products are the work of one person.
A final-year medical student, building what the ward kept needing.
Every product here started as a job I was already doing — clerking, revising for finals, hunting one paper at one in the morning. I build in the open and publish what the measurement said — including the runs that went against me.
Ten products and nine published libraries, taken from a problem to something running. I have been the whole team on every one of them — the architecture, the schema, the interface and the deploy. Either I do that work with a team around me, or I do it with the funding to put these in front of the people they were built for. Both interest me; the building happens regardless.
